Abstract: A low temperature device has a low temperature container with an investigational opening. A material sample to that is to be examiner is mounted on a sample-holding device in the low temperature container. A sample that is fastened to the sample holding device can be cooled to the desired temperature using a cooling device, such as a pulse tube cooler, with a cold head that is inside the low temperature container. The sample holder is disposed in the low temperature container in such a way that the sample can be seen through the investigational opening. Because the investigational opening is flexible and not rigidly connected to the low temperature container, vibrations produced by the mechanical cooling device are prevented from being transferred to the investigational opening. Thus, a vibration-sensitive investigating and manipulating device can be coupled to the investigational opening without vibrations being transferred to the investigating and manipulating device.
